• nginx: js file loads indifferently every refresh

  - by poymode

  I have this nginx problem wherein a js file in a rails app loads indifferently. Whenever I try to access the JS file in the browser and refresh the page, the scrollbar changes length meaning sometimes it loads half the js page, sometimes the whole and sometimes just a part of it. the js file size is 71K. my nginx server is on different server,separate from my rails app. when I try to access the js file directly through the app server, lets say 10.48.30.150:3000/javascripts/file.js it works fine and doesnt show any half-loaded page. but when I use the nginx server which upstreams the rails app, it shows the indifferent page loads. here is my nginx http conf error_log /usr/local/nginx/logs/error.log; pid /usr/local/nginx/logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 256; access_log /usr/local/nginx/logs/access.log; sendfile on; #tcp_nopush on; keepalive_timeout 0; tcp_nodelay on; #gzip on; #gzip_min_length 4096; #gzip_buffers 16 8k; #gzip_types application/x-javascript text/css text/plain; large_client_header_buffers 4 8k; client_max_body_size 2G; include /usr/local/nginx/conf.d/*.conf; }

• Apache https is slow

  - by raucous12

  Hey, I've set apache up to use SSL with a self signed certificate. With https (KeepAlive on), I can get over 3000 requests per second. However, with https (KeepAlive off), I can only get 13 requests per second. I know there is supposed to be a bit of an overhead, but this seems abnormal. Can anyone suggest how I might go about debugging this. Here is the ab log for https: Server Software: Apache/2.2.3 Server Hostname: 127.0.0.1 Server Port: 443 SSL/TLS Protocol: TLSv1/SSLv3,DHE-RSA-AES256-SHA,4096,256 Document Path: /hello.html Document Length: 29 bytes Concurrency Level: 5 Time taken for tests: 30.49425 seconds Complete requests: 411 Failed requests: 0 Write errors: 0 Total transferred: 119601 bytes HTML transferred: 11919 bytes Requests per second: 13.68 [#/sec] (mean) Time per request: 365.565 [ms] (mean) Time per request: 73.113 [ms] (mean, across all concurrent requests) Transfer rate: 3.86 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 190 347 74.3 333 716 Processing: 0 14 24.0 1 166 Waiting: 0 11 21.6 0 165 Total: 191 361 80.8 345 716 Percentage of the requests served within a certain time (ms) 50% 345 66% 377 75% 408 80% 421 90% 468 95% 521 98% 578 99% 596 100% 716 (longest request)

• Disk fragmentation when dealing with many small files

  - by Zorlack

  On a daily basis we generate about 3.4 Million small jpeg files. We also delete about 3.4 Million 90 day old images. To date, we've dealt with this content by storing the images in a hierarchical manner. The heriarchy is something like this: /Year/Month/Day/Source/ This heirarchy allows us to effectively delete days worth of content across all sources. The files are stored on a Windows 2003 server connected to a 14 disk SATA RAID6. We've started having significant performance issues when writing-to and reading-from the disks. This may be due to the performance of the hardware, but I suspect that disk fragmentation may be a culprit at well. Some people have recommended storing the data in a database, but I've been hesitant to do this. An other thought was to use some sort of container file, like a VHD or something. Does anyone have any advice for mitigating this kind of fragmentation? Additional Info: The average file size is 8-14KB Format information from fsutil: NTFS Volume Serial Number : 0x2ae2ea00e2e9d05d Version : 3.1 Number Sectors : 0x00000001e847ffff Total Clusters : 0x000000003d08ffff Free Clusters : 0x000000001c1a4df0 Total Reserved : 0x0000000000000000 Bytes Per Sector : 512 Bytes Per Cluster : 4096 Bytes Per FileRecord Segment : 1024 Clusters Per FileRecord Segment : 0 Mft Valid Data Length : 0x000000208f020000 Mft Start Lcn : 0x00000000000c0000 Mft2 Start Lcn : 0x000000001e847fff Mft Zone Start : 0x0000000002163b20 Mft Zone End : 0x0000000007ad2000

• How to divert traffic based on hostname using HAProxy?

  - by Bosky

  I've had some initial success with HAProxy setting up a bunch of app servers listening on various other ports. I now have another webserver listening on one port, and i'd like to what changes to make to my config to flow traffic by hostname as well. The following is the current setup, assuming: my apache webserver is running at examplecom:8001 my bunch of app servers 0.0.0.0:8081, 0.0.0.0:8082 , 0.0.0.0:8083 global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 debug #quiet #user haproxy #group haproxy defaults log global mode http option httplog option dontlognull retries 3 redispatch maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 listen appservers 0.0.0.0:80 mode http balance roundrobin option httpclose option forwardfor #option httpchk HEAD /check.txt HTTP/1.0 server inst1 0.0.0.0:8081 cookie server01 check inter 2000 fall 3 server inst2 0.0.0.0:8082 cookie server02 check inter 2000 fall 3 server inst3 0.0.0.0:8083 cookie server01 check inter 2000 fall 3 server inst4 0.0.0.0:8084 cookie server02 check inter 2000 fall 3 capture cookie vgnvisitor= len 32 (any other comments on the ^ setup are welcome.) Now I'd like to continue the same above, but in addition in case - if the hostname is myspecialtopleveldomain<dot>com, then would like to flow traffic to example<dot>com:8001 ~B

• Google Chrome on Linux not using ALSA for sound

  - by DarkMoon

  On my laptop, I've got an .asoundrc file that outputs sound to my USB headset. This works fine for SMplayer and Firefox. However, Google Chrome (at least, Flash-based and HTML5-based videos and HTML5-based audio in Chrome) plays through the laptop speakers instead. I've tried running Chrome from a command-line, hoping there would be some helpful output, but no such luck. I've tried looking through Google for whether Chrome even uses ALSA, or if it uses something else, but I have been unsuccessful in this. This question seems to be the same issue, but no suggestion was made. Anyone have any ideas? I'm running Gentoo with a 3.10.17 kernel, 1.0.27 ALSA utils, 2.6.5 FVWM, and 36.0.1985.143 Chrome. If you need more info, please let me know. EDIT: I've configured the USB headset as the default ALSA device. Volume levels for both headset and onboard are set and un-muted using alsamixer. My .asoundrc file is as follows. ctl.!default { type hw card Headset } pcm.dmixer { type dmix ipc_key 1024 slave { pcm { type hw card Headset } period_size 1024 buffer_size 4096 } bindings { 0 0 1 1 } } pcm.!default { type plug slave.pcm dmixer }

• Ubuntu 12.04 VirtualBox on powerful W7 quite slow

  - by wnstnsmth

  I own a Thinkpad T420s with 8GB RAM, 160 GB SSD and a quite fast i7 processor. Summa summarum a very fast computer that works perfectly. Now, I am not very impressed by the performance of my Ubuntu 12.04 virtual machine running on VirtualBox 4.1.18. I assume that Virtual Machines are always a bit slower than the guest system, still I think it should be more performant given the hardware settings I give it: 4096 MB RAM 1 CPU without CPU limitation (I would like to give it more but then it does not seem to work - I am not experienced in this maybe somebody could give me advice on this too) Activated PAE/NX, VT-x/AMD-V and Nested Paging 96 MB Graphics Memory (no 2D or 3D acceleration) ~ 14 GB disk space, currently about 7 GB are used Maybe I misconfigured something, could you give me a hint please? Thanks! Edit: What I mean by slow is that for example switching tabs in the browser (whether FF or Chrome) only goes with a 0.5s delay or something, as well as switching application windows and/or double-clicking applications in the dock to get all open windows.. opening Aptana takes about a minute whereas opening something like Photoshop on the guest system takes 5 seconds

• mdadm lvm and ext4 slowness - How can I speed it up?

  - by beatbreaker

  I can't figure out why I'm getting such terrible times out of my mdadm and in particular the lvm partitions in it. I made the raid: mdadm --create --verbose /dev/md0 --level=5 --chunk=1024 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 # cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md0 : active raid5 sda1[0] sdd1[3] sdc1[2] sdb1[1] 2930279424 blocks level 5, 1024k chunk, algorithm 2 [4/4] [UUUU] I then created the physical volume, volume group, and logical volumes, I then formatted the logical volumes to ext4 using the following commands I got from here: http://busybox.net/~aldot/mkfs_stride.html mkfs.ext3 -b 4096 -E stride=256,stripe-width=768 /dev/datavg/blah Now I'm confused, I had these lvs running real quick before in mdadm but now that I've 'optimized' everything it's slower, eg, before: /dev/datavg/lv_audio: Timing buffered disk reads: 598 MB in 3.01 seconds = 198.85 MB/sec but now after: /dev/datavg/audio: Timing buffered disk reads: 198 MB in 3.00 seconds = 65.96 MB/sec That's pitiful! What's happened here? Did I not follow the instructions correctly? Can i reshape the ext4 partitons to default back to what they were? (I used defaults before and they were fine!)

• Nginx and client certificates from hierarchical OpenSSL-based certification authorities

  - by Fmy Oen

  I'm trying to set up root certification authority, subordinate certification authority and to generate the client certificates signed by any of this CA that nginx 0.7.67 on Debian Squeeze will accept. My problem is that root CA signed client certificate works fine while subordinate CA signed one results in "400 Bad Request. The SSL certificate error".

• SQL SERVER – Introduction to Extended Events – Finding Long Running Queries

  - by pinaldave

  The job of an SQL Consultant is very interesting as always. The month before, I was busy doing query optimization and performance tuning projects for our clients, and this month, I am busy delivering my performance in Microsoft SQL Server 2005/2008 Query Optimization and & Performance Tuning Course. I recently read white paper about Extended Event by SQL Server MVP Jonathan Kehayias. You can read the white paper here: Using SQL Server 2008 Extended Events. I also read another appealing chapter by Jonathan in the book, SQLAuthority Book Review – Professional SQL Server 2008 Internals and Troubleshooting. After reading these excellent notes by Jonathan, I decided to upgrade my course and include Extended Event as one of the modules. This week, I have delivered Extended Events session two times and attendees really liked the said course. They really think Extended Events is one of the most powerful tools available. Extended Events can do many things. I suggest that you read the white paper I mentioned to learn more about this tool. Instead of writing a long theory, I am going to write a very quick script for Extended Events. This event session captures all the longest running queries ever since the event session was started. One of the many advantages of the Extended Events is that it can be configured very easily and it is a robust method to collect necessary information in terms of troubleshooting. There are many targets where you can store the information, which include XML file target, which I really like. In the following Events, we are writing the details of the event at two locations: 1) Ringer Buffer; and 2) XML file. It is not necessary to write at both places, either of the two will do. -- Extended Event for finding *long running query* IF EXISTS(SELECT * FROM sys.server_event_sessions WHERE name='LongRunningQuery') DROP EVENT SESSION LongRunningQuery ON SERVER GO -- Create Event CREATE EVENT SESSION LongRunningQuery ON SERVER -- Add event to capture event ADD EVENT sqlserver.sql_statement_completed ( -- Add action - event property ACTION (sqlserver.sql_text, sqlserver.tsql_stack) -- Predicate - time 1000 milisecond WHERE sqlserver.sql_statement_completed.duration > 1000 ) -- Add target for capturing the data - XML File ADD TARGET package0.asynchronous_file_target( SET filename='c:\LongRunningQuery.xet', metadatafile='c:\LongRunningQuery.xem'), -- Add target for capturing the data - Ring Bugger ADD TARGET package0.ring_buffer (SET max_memory = 4096) WITH (max_dispatch_latency = 1 seconds) GO -- Enable Event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=START GO -- Run long query (longer than 1000 ms) SELECT * FROM AdventureWorks.Sales.SalesOrderDetail ORDER BY UnitPriceDiscount DESC GO -- Stop the event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=STOP GO -- Read the data from Ring Buffer SELECT CAST(dt.target_data AS XML) AS xmlLockData FROM sys.dm_xe_session_targets dt JOIN sys.dm_xe_sessions ds ON ds.Address = dt.event_session_address JOIN sys.server_event_sessions ss ON ds.Name = ss.Name WHERE dt.target_name = 'ring_buffer' AND ds.Name = 'LongRunningQuery' GO -- Read the data from XML File SELECT event_data_XML.value('(event/data[1])[1]','VARCHAR(100)') AS Database_ID, event_data_XML.value('(event/data[2])[1]','INT') AS OBJECT_ID, event_data_XML.value('(event/data[3])[1]','INT') AS object_type, event_data_XML.value('(event/data[4])[1]','INT') AS cpu, event_data_XML.value('(event/data[5])[1]','INT') AS duration, event_data_XML.value('(event/data[6])[1]','INT') AS reads, event_data_XML.value('(event/data[7])[1]','INT') AS writes, event_data_XML.value('(event/action[1])[1]','VARCHAR(512)') AS sql_text, event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS tsql_stack, CAST(event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS XML).value('(frame/@handle)[1]','VARCHAR(50)') AS handle FROM ( SELECT CAST(event_data AS XML) event_data_XML, * FROM sys.fn_xe_file_target_read_file ('c:\LongRunningQuery*.xet', 'c:\LongRunningQuery*.xem', NULL, NULL)) T GO -- Clean up. Drop the event DROP EVENT SESSION LongRunningQuery ON SERVER GO Just run the above query, afterwards you will find following result set. This result set contains the query that was running over 1000 ms. In our example, I used the XML file, and it does not reset when SQL services or computers restarts (if you are using DMV, it will reset when SQL services restarts). This event session can be very helpful for troubleshooting. Let me know if you want me to write more about Extended Events. I am totally fascinated with this feature, so I’m planning to acquire more knowledge about it so I can determine its other usages.

• Can't boot 12.04 installed alongside Windows 7

  - by PalaceChan

  I realize there are other questions like this one here, but I have visited them and tried several things and nothing is helping. One of them had a suggestion to boot the liveCD, and sudo mount /dev/sda* /mnt and to then chroot and reinstall grub. I did this and it did not help. Then on the Windows side, I downloaded a free version of easyBCD and chose to add a Grub2 Ubuntu 12.04 entry. On restart I saw this entry, but when I click on it it takes me to a Windows failed to boot error, as if it wasn't even trying to boot Ubuntu. I have booted from Ubuntu liveCD once again and have a snapshot of my GParted I ran this bootinfoscript thing from the liveCD, here are my results: It seems grub is on sda.

• UPOS RFIDScanner data format

  - by Robert Snyder

  A lot of work that I do currently is based in the OPOS/UPOS world. My company has a device that can read 13.56Mhz tags (RFID), Smart Cards, and Mag Stripe cards. Up until somewhat recently I have only been working with RFID for a very specific scenario. That was to read UltraLight C and Desfire cards. These cards were all setup very specifically so that I could take the data read from those cards and force it into a MSR track2 format. The past couple of weeks, however, I have been working on reading RFID credit cards (since I have a Visa card I've been using mine), and Smart Card credit cards. (The visa card I have has both) In learning how to communicate with SmartCard and reading ISO7816 and EMVCO documents I became a little more familiar with how info is stored. But now I have a question regarding UPOS. The RFID data on my Visa is stored (and read) very similar to how the data is stored and read from the Smart Card on my Visa. Cool. Well in the UPOS spec for SmartCardRW the ReadData method returns a byte array. That's cool, I can just return all that data and then parse it as my heart desires. The RFID though has a LinkedList of Tags. Well this makes sense in terms of my Visa card (reminds me of a question I have in regards to SmartCard, but that is for another question) but what about ULC and Desfire, or for that matter any Mifare card. Pages, Files, Purses don't exactly fit the Tag profile. For instance lets just say I read pages 4-12 on my ULC card. Each page I read is 4 bytes long. Does this mean I have 9 tags in my LinkedList? Is my Tag id the page number? Or then how does that translate to Desfire? I open application 123456 and read file 1 and file 2, Do I have 2 tags? and if so what is my tag id? At least with my Visa I think that I have to use the Tag id (ex 5F24 for my expiration date) and value of {0x15, 0x10, 0x31} Part of me says yes..that makes sense. Another part of me says, "well if that is the case then why doesn't SmartCardRW have Tags?" So that is my question. How do I format my data from those different types of media? or is that the job of my Control Object (the application)? Is so how does it know? The only protocols I have are: // Summary: // Enumerates the available predefined RFID tag protocols the device supports. [Flags] public enum RFIDProtocols { EpcClass0 = 1, RFIDSdt0Plus = 2, EpcClass1 = 4, EpcClass1Gen2 = 8, EpcClass2 = 16, Iso14443A = 4096, Iso14443B = 8192, Iso15693 = 12288, Iso180006B = 16384, Other = 16777216, All = 1073741824, } If I use that well all of my cards that I have are all Iso14443A. I use the ATQA and the SAK to know what type of card I really have. There is no RFID property that lets me specify that. So I'm lost.

• Problems with WCF reliable session (reliable messaging)

  - by Rob

  Hi, In our WCF application I am trying to configure reliable sessions. Service: <wsHttpBinding> <binding name="BindingStabiHTTP" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152" messageEncoding="Text"> <reliableSession enabled="true" ordered="true" inactivityTimeout="00:10:00"/> <readerQuotas maxDepth="0" maxStringContentLength="0" maxArrayLength="0" maxBytesPerRead="0" maxNameTableCharCount="0" /> </binding> </wsHttpBinding> Client: <wsHttpBinding> <binding name="BindingClientWsHttpStandard" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="true" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> Unfortunately I get an error which is as follows: No signature message parts were specified for messages with the 'http://schemas.xmlsoap.org/ws/2005/02/rm/CreateSequence' action. If I disable the reliableSession on the client I get this message: The action is not supported by this endpoint. Only WS-ReliableMessaging February 2005 messages are processed by this endpoint. So it seems that the server is configured correctly for RM. I cannot find anything valuable about the error I get so I don't know how to fix this. Any ideas what can be wrong? Thank in advance, Rob

• WCF Maximum Read Depth Exception

  I get the following exception when trying to pass a DTO over WCF services. System.Xml.XmlException: The maximum read depth (32) has been exceeded because XML data being read has more levels of nesting than is allowed by the quota.

• Consume a WCF Web Service in Sharepoint Services 3.0

  - by Filip Ekberg

  I've seen this question and since it doesn't answer my question and the topic is fairly miss-leading in my opinion, I feel the urge to ask this again. I have a Sharepoint Webpart that I deploy using Visual Studio Sharepoint Tools 1.2 to a Sharepoint Services 3.0 instance on my local Windows 2003 server. All works great, however, as soon as I add a WCF Service it won't run the code. All I get is a File not found error. I've added this to my Web.Config which is a copy of App.Config <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_Services_xxxService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Mtom" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:1196/xxxService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ervices_xxxgService" contract="xxxService.TestService" name="BasicHttpBinding_ServicesxxxService" /> </client> </system.serviceModel> I cannot even do using(var proxy = new xxService.TestService()), If that line is added, the new dll is not added to Sharepoint Services. Any suggestions? I also found this blog post and this forum thread, don't think they are too helpful though.

• C# CreatePipe() -> Protected memory error

  - by M. Dimitri

  Hi all, I trying to create a pipe using C#. The code is quite simple but I get a error saying "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Here the COMPLETE code of my form : public partial class Form1 : Form { [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool CreatePipe(out SafeFileHandle hReadPipe, out SafeFileHandle hWritePipe, SECURITY_ATTRIBUTES lpPipeAttributes, int nSize); [StructLayout(LayoutKind.Sequential)] public struct SECURITY_ATTRIBUTES { public DWORD nLength; public IntPtr lpSecurityDescriptor; public bool bInheritHandle; } public Form1() { InitializeComponent(); } private void btCreate_Click(object sender, EventArgs e) { SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES(); sa.nLength = (DWORD)System.Runtime.InteropServices.Marshal.SizeOf(sa); sa.lpSecurityDescriptor = IntPtr.Zero; sa.bInheritHandle = true; SafeFileHandle hWrite = null; SafeFileHandle hRead = null; if (CreatePipe(out hRead, out hWrite, sa, 4096)) { MessageBox.Show("Pipe created !"); } else MessageBox.Show("Error : Pipe not created !"); } } At the top I declare : using DWORD = System.UInt32; Thank you very much if someone can help.

• Using Freepascal\Lazarus JSON Libraries

  - by Gizmo_the_Great

  I'm hoping for a bit of a "simpletons" demo\explanation for using Lazarus\Freepascal JSON parsing. I've asked a question here but all the replies are "read this" and none of them are really helping me get a grasp because the examples are bit too in-depth and I'm seeking a very simple example to help me understand how it works. In brief, my program reads an untyped binary file in chunks of 4096 bytes. The raw data then gets converted to ASCII and stored in a string. It then goes through the variable looking for certain patterns, which, it turned out, are JSON data structures. I've currently coded the parsing the hard way using Pos and ExtractANSIString etc. But I'vesince learnt that there are JSON libraries for Lazarus & FPC, namely fcl-json, fpjson, jsonparser, jsonscanner etc. https://bitbucket.org/reiniero/fpctwit/src http://fossies.org/unix/misc/fpcbuild-2.6.0.tar.gz:a/fpcbuild-2.6.0/fpcsrc/packages/fcl-json/src/ http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/packages/fcl-json/examples/ However, I still can't quite work out HOW I read my string variable and parse it for JSON data and then access those JSON structures. Can anyone give me a very simple example, to help getting me going? My code so far (without JSON) is something like this: try SourceFile.Position := 0; while TotalBytesRead < SourceFile.Size do begin BytesRead := SourceFile.Read(Buffer,sizeof(Buffer)); inc(TotalBytesRead, BytesRead); StringContent := StripNonAsciiExceptCRLF(Buffer); // A custom function to strip out binary garbage leaving just ASCII readable text if Pos('MySearchValue', StringContent) > 0 then begin // Do the parsing. This is where I need to do the JSON stuff ...

  Hi, I am trying to connect to a web service served by SAP and i have authentication problem.

  I just installed NetBeans and the Android SDK following the instructions here. I am running Ubuntu 9.10 (Karmic). NetBeans is 6.7.1. The Android SDK is version 7.

• Will HttpResponse.Filter buffer the whole data before start the sending?

  - by vtortola

  Hi, An user posts this article about how to use HttpResponse.Filter to compress large amounts of data. But what will happen if I try to transfer a 4G file? will it load the whole file in memory in order to compress it? or otherwise it will compress it chunk by chunk? I mean, I'm doing this right now: public void GetFile(HttpResponse response) { String fileName = "example.iso"; response.ClearHeaders(); response.ClearContent(); response.ContentType = "application/octet-stream"; response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName); response.AppendHeader("Content-Length", new FileInfo(fileName).Length.ToString()); using (FileStream fs = new FileStream(Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data"), fileName), FileMode.Open)) using (DeflateStream ds = new DeflateStream(fs,CompressionMode.Compress)) { Byte[] buffer = new Byte[4096]; Int32 readed = 0; while ((readed = ds.Read(buffer, 0, buffer.Length)) > 0) { response.OutputStream.Write(buffer, 0, readed); response.Flush(); } } } So at the same time I'm reading, I'm compressing and sending it. Then I wanna know if HttpResponse do the same thing, or otherwise it will load the whole file in memory in order to compress it. Cheers.

• Problem with WCF Streaming

  - by H4mm3rHead

  Hi, I was looking at this thread: http://stackoverflow.com/questions/1935040/how-to-handle-large-file-uploads-via-wcf I need to have a web service hosted at my provider where i need to upload and download files to. We are talking videos from 1Mb to 100Mb hence the streaming approach. I cant get it to work, i declared an Interface: [ServiceContract] public interface IFileTransferService { [OperationContract] void UploadFile(Stream stream); } and all is fine, i implement it like this: public string FileName = "test"; public void UploadFile(Stream stream) { try { FileStream outStream = File.Open(FileName, FileMode.Create, FileAccess.Write); const int bufferLength = 4096; byte[] buffer = new byte[bufferLength]; int count = 0; while((count = stream.Read(buffer, 0, bufferLength)) > 0) { //progress outStream.Write(buffer, 0, count); } outStream.Close(); stream.Close(); //saved } catch(Exception ex) { throw new Exception("error: "+ex.Message); } } Still no problem, its published to my webserver out on the interweb. So far so good. Now i make a reference to it and will pass it a FileStream, but the argument is now a byte[] - why is that and how do i get it the proper way for streaming? Edit My binding look like this: <bindings> <basicHttpBinding> <binding name="StreamingFileTransferServicesBinding" transferMode="StreamedRequest" maxBufferSize="65536" maxReceivedMessageSize="204003200" /> </basicHttpBinding> </bindings> I can consume it without problems, and get no errors - other than my input parameter has changed from a stream to a byte[]
